COMPOSITION TO ASSIST IN .DYEING AND FINIL IHING OPERATIONS.

No Drawing. Application filcd September To all whom it may concern. i 7

Be it known that I, SEYh [OLUR M. Hm:-

-1\IANN, a citizen of the United States, and a resident of New York, in the county and tate of New York, have invented new and useful Improvements in Composition to As sist in Dyeing and Finishing Operations, of which the following is a specification. v

This invention relates to a composition that isused to assist in dyeing and also finishing operations, that is known by the term ingresene, The object of this invention is to provide a composition that will cause dyes and similar compounds to quickly and readily penetrate and assimilate the various materials to which the dyes applied, and which penetration is effected with the employment of much less temperature and time, labor, steam, or heat, and the dyeing operation is carried out at a much reduced expense.

This composition is formed of two components. One of these components is formed by treating any kind of hops, or humulus, or lupulus, or lupulin, with some form of alcohol, of any preferred kind, such as amyl alcohol and denatured alcohol. This material, in the nature of hops, is mixed with some alcohol, in about proportions of thirty parts of the hops to one hundred parts of the alcohol and water, about three parts of alcohol to one part of water. The hops are percolated with the alcohol, and this is stirred several times, for a period of about a week, and then again percolated, and run off, which forms the fluid extract of the hops, and this is employed as astock liquor.

The second ingredient of my composition consists of an extract from the gall of any animal. The extract is preferably made by using about ten parts of gall in the raw state, that is boiled in water for several hours, preferably in about the proportion of 50 parts of water.

This extract of gall is then mixed with the extract from the hops and alcohol, in about equal proportions of these ingredients, then allowed to settle, and then filtered.

In the use of the compound for dyeing of animal fibres, the dye bath is prepared in the usual way, and the previously dissolved dyestulf is added, and then the compound is added in the proportion of about 2 to 5%, according to the tightness of the weave or twist. T 1e boiling is gradual with the ad- 19, 1925. Serial No. 57,468.

dition of theusual salts, acids, etc., and the process carried on in the usual manner.

For vegetable and 'mixed'fibres a similar the usual methods employed, as". the compound will work with the acids, salts, etc., generally employed in this art. The dye bat-h can be prepared cold, with the usual proportions of Glauber salts, and dyestuffs previously dissolved, and then from 3 to 5% of the compound is added according to the thickness of the material. This process is improved by the addition of acetic and sulphuric acids, and process continued for about fifteen minutes. If the penetration of the color is not complete, continue with the dyeing until the desired results are obtained. This process assures level dy-eings, quick penetration of the color, fuller shades, and permits dyeing at ailower temperature in one half the usual time employed. Hats which ordinarily take from two to three hours can be dyed in One hour. The expense of using the compound is more than offset by the increased production obtained, and the saving of time, labor, steam, etc. The reduced time of boiling as a result of the shorter dyeing time, is advantageous to the size in the hat, and the fur.

It will be seen that my compound, has

wonderful penetrative properties and can be used for practically all varieties of dye oper ations. It appears to carry the color of the dye into the pores and cells of the substances and deposits them at such places with uniformity of shade.

Treatment with my compound assures penetration of the dye, with level dyeings and fuller shades in one-half of the time ordinarily required. Textiles which require approximately two hours for the proper penetration of the color, can be dyed in one hour, when the compound is added to the dye bath. This process is of special advantage for tight woven fabrics or tight twisted yarns where penetration is diflicult or requires prolonged boiling. employing ingresene is more than ofiset by the saving resulting from the increased prolOS The expense of duction, and saving of time, steam and handling.

The compound will be found equally adaptable for wool, silk cotton, linen, or other fabrics, leather or stufi's, or mixed fibres, and especially advantageous where the fibre is such that a low dyeing tempera ture is necessary or preferable. In the dyeing of textiles with vat colors, where loW tempe'atures are employed, a still lower temperature can be used with the use of the compound. The compound serves as an assist in accelerating the penetration of the colors and dissolving same and for level dyeings. lVhere shoddy is dyed in the machine, the use of the compound permits the dyeing of a much greater amount of stock than usual, assuring excellent penetration, and level dyeings.

What I claim is:

1. A composition to assist in dyeing operations, that is composed of a solution prepared by extracting hops with alcohol, to which is added a solution prepared from gall by boiling in water, said components being mixed about equal proportions of said two ingredients.

2. A composition to assist in dyeing operations, comprising a solution prepared by extracting hops with alcohol, to which is added a solution formed by boiling gall in water, the two components being mixed in about the equal proportions of said two ingredients.

3. A composition to assist in dyeing operations, that is composed of a solution prepared by extiacting hops with alcohol, to which is added a solution prepared from gall in water.

4. A composition to assist in dyeing operations, comprising a solution prepared by extracting hops with alcohol, to which is added a solution prepared from gall in water.

A compositionto assist in dyeing oper ations, that contains a solution prepared by extracting hops with alcohol.
